I also uncovered that certain high-RTP slots that typically form the backbone of my cash play were explicitly blocked from bonus wagering at the time of my review, a widespread industry practice. This pushed me to pivot to the next tier of eligible games, weighing RTP against variance so I could finish the playthrough without depleting the bonus funds. I never accept a promotion until I have cross-referenced the eligible game list, and at Spinstralia that preliminary work averted a unpleasant forfeiture later.
